Display
The line devices are displayed in the order of the loop. On the branch to the sub-
stub, the line devices are displayed in the order of the sub-stub. The display shows
the number of the line device in brackets. E.g. [T003] for the third line device. In the
case of the red outlined device, the internal alarm indicator flashes. If an external
alarm indicator is connected to this device, the external alarm indicator also
flashes.
